Just when you think that Scott can’t possibly come up with something new and exciting, he never falls to amaze everyone. Since I’m not familiar with this particular weapon, I’m going to use other sources for all of the ‘tech’ stuff so that I don’t get anything wrong and you get the straight scoop!
This bit of info comes from Wikipedia:
“8.6 mm Blackout (8.6×43 mm), also sometimes referred to as 8.6 BLK or 8.6 Creedmoor, is a centerfire rifle cartridge developed by the firearms manufacturer Q. It utilizes a shortened case from the 6.5mm Creedmoor necked up to an 8.6 mm caliber (8.585 mm or 0.338 in diameter) projectile and designed for use in bolt action rifles or as a caliber conversion for AR10 and AR-308 rifles. The 8.6 Blackout has been designed for barrels using a 76 mm or 102 mm (1:3 in or 1:4 in) twist rate and bullet weights between 10.4–14.6 g (160–225 gr) for supersonic loads and 18.5–22.7 g (285–350 gr) for subsonic loads.”
Like the 300 Blackout, the 8.6 Blackout was designed primarily for suppressed shooting, however, they also have supersonic loads in development as well. 8.6 BLK is re-imagining “energy on target” by employing a fast 1:3 twist rate.
Faxon Firearms has recently announced that their Sentinel series of AR-10 pattern semi-auto rifles chambered in 8.6 Blackout is now available for preorder.You can click HERE and go directly to their website.
This nex bit of info comes from Gorilla Ammunition:
“8.6 Blackout was developed by Kevin Brittingham and his team at Q. It is often referred to as 300 Blackouts big brother and its easy to see why. What 300BLK provided to the AR-15 platform, 8.6BLK does for AR-10’s. The parent case being 6.5 Creedmoor, 8.6BLK is trimmed down and necked up for a .338 projectile. Heavier mass means more energy transfer on target. Barrels are being run with a fast 1:3 twist, creating devastating terminal performance. Although 8.6BLK is larger than its 300BLK brother, our subsonic ammunition offerings make it just as quiet. To learn more, click HERE.”
